OIL-BURNER.

Patent-cd May 1 3, 1 913. serial No. 722,961.

To all I101mm, 'it may foncer/t Be it known that I, Geenen Lewis llenan, a citizen, of the United States, residing a t 5G Sherbrooke street west,Y hfontreal, Province of Quebec, Canada, have invented certain new and useful Improvements in ()il Burners; and l do hereby declare that the following is a full, clear, and exact de` seri tion of the same.

` lVl)y invention relates to improvements in oil burners wherein the oil is converted into vapor which is consumed to promote heat for heating or cooking purposes.

yCertain of the objects of my invention are to provide means for rst converting the oil into vapor and then into gas and to finally draw a supply of air from the ex terior of the combustion chamber ot' the burner and mix the same with the gas prior to the ignition of the latter; and also to provide an .immediate regulation of the oil supply by controlling such supply at the outlet of the pipe to the vaporizing apparatus.

Further objects and advantages will be hereinafter described and particularly pointed out in the claims. i

For full comprehension, however, of my invention reference must be had to the accompanying drawings forming a part of (his specification, in which .like reference characters indicate the same parts and wherein:

Figure l is a vertical sectional view of my improved burner; Fig. 2 is a plan view oi the gas chamber with the upper portion partly broken away; and Fig. 3 is a section taken on line 3-3'Fig. Q and including the raporizing chamber.

Broadly speaking' my burner comprises an oil supply pipe which is in communication with a gas chamber, while intermediate ot the supply pip'e and gas chamber is located a vaporizing chamher. The gas chamber communicates with a burner which receives a supply of air and is constructed .so as 'to present a mixing chamber wherein the gas or vapor and air is first mingled and then passes to the point where it is ignited.

improved oil t t pau, being connected to Referring now to` the drawings, indicates a casing or combustion chamber which is preferably supported on legs c and has an outlet l while c indicates an oil reservoir which is suitably supported adjacent to and pret'e v'ably above the casing and communicates with the oil converting and burning apl'iaratus by a pipe or tubing e. The present apparatus may be used with or without the casing b.

The oil supply pipe f is connected to the pipe e by a needle valve g and extends from outside the casing, in a preferably horizontal line to a point within the latter, terminating in an outlet lying at an angle to the pipe and referably formed as a downwardly curve drip outlet 4 and being inclosed by a pipe or'chamber li and supported within the-latter by plugs z' and' j at the ends of the same. The oil supply pipe is `preferably of small bore and -terminatee` within a pipe or chamber c eX- tending from and supported by the plug j and constituting the vaporizing chamber.

The chamber Il: is coupled or otherwise connected to a gas forming chamber having a tortuous passage formed therein. The gas chamber maybe of any desired form but I prefer to construct it in two rectangular parts bolted or otherwise fastened together. The bottom portion Z has formed therein a passage m which'communicatcs at one end with the chamber 7c and extends in atortuous path therefrom to a pipe n leading to the burner. The top portion o comprises a cover for the portion Z to which it is secured by bolts p while a sheet (1 of asbestos or like insulating material is interposed between the two portions. The top portion is directly connected to the chamber c through the medium of an annular flange le and has a vent r therein leading from the latter t0 the passage m while a series ot' ribs s upon the top of the upper portion form a pan if `t'or spirits which are adapted to be. -ignited to initially heat'and'so vaporize the oil in the chamber 7c from which it passes to the passage m. The chamber l.: as clearly seen in Fig. 1, extends over 'the the gas chamber warping f the V regulated by 't0 apply maybe removed and the pipe cleaned or an eXtra burner coupled to pipe a.

is obtained the flow is stopped by closing preferably will deflect the path of the oil out of the line of thepipe at a point adjacent to the outlet, always catching the drain of the oil sup ly, and keeping the outlet end of the pipe lfdd, in which condition the oil at the outlet 4 will as the pressure rises be influenced and rectly controlled by the back pressure and so Ribs u prevent near the middle thereof. reinforce thesides ofthe pan t and latter when heated. The b `ner is preferably located below the gas chamber so that the latter will be flame from the burner which exposed to. the will heat the latter 'producing vapor or gas in the passage m. he pipe. ln.1nay be conprevent the feeding of the oil after the gas nected to the gas chamber through the mehas reached a certain pressure. In like mandium of a coupling lv integral with the latner when more oil is required the feed will ter; The pipe n extends to the burner be immediate.

which includes a vertically disposed tip w. The operation of my improved oil burner Instead of mixing the gas or vapor comis as follows: Spirit-s such as alcohol is put into the pan t and ignited to primarily heat the chamber v and thc oil supply is started, the oil being vaporized in the heated cham-v ber. `l1e vapor and possibly some oil then passes through the gas chamber, pipe n, a and tip fw when mingling with the air in ing from the tip fw with the more or less gas laden air inside the casing I have formed a chamber a: inclosing the tip and supplied with air from the exterior` of the casing. The chamber w is protected at the top, at which point the ignition of the gas takes place, by one or more but preferably chamber it passes out through the screens two screens 2 and 3, one a disk and the other l2 and 3 and is ignited,- the flame resulting either a curved or defiected screen-which therefrom playing upon. the gas chamber prevent back flashing. The lower en of h eatin the same and so converting a porthe chamber w is in communication with the tion o the vapor passing through the tortuous passage m into gas which passes' through pipe n, n to the ti and in lily manner as the preliminary mingles with the air in the chamber w and is consumed at 3. The heat derived from the burning alcohol, is merely temporary as the flame 3 continues the heating of such chamber when the alcohol has been consumed'.l lIf vthe heat lfrom the burnerbecomes too intense a plate or screen 10 may be interposed between the burner and gas chamber. By providing the chamber w wherein air from the eX- terior of the casing is mixed with the gas or v apor prior1to the ignition of the latter, a blue lor Bunsen flame is produced which. is capable of generating an intense heat.

What I claim is as follows: i 1. In lan'oil burner, the combination with a combustion chamber and an oil inlet, of a vapor-izing chamber, an oil supply passage leading from the oil inlet tothe vaporizing locate exterior of the casing by means of a conduit 5 which includesthe chamber h andpasses at the same point asthe is provided with an air 1n casing. The sup ly of air to the conduit is a amper 6. The conduit is also provided with an auxlliary airvent 8 .which communicates with the interior of the casing and is protected by heavy screen or perforated plate 9 t'o prevent back iiashing although this vent is only necessary v'when conditions will notpermit the use o lthe full capacity of the inlet' as for instance, when the burner is located in a conned space, and there is not suliicient space as large a damper fitting as is shown 1n the drawings.

The pipe n is preferably constructed to present a straight portion a adjacent to the tip lw and is provided with a plug 7 which A vent d 1n- 10 is located in the bottom of chamber m to carry ofi' any oil that may collect in the latter.

Gas or vapor is generated in proportion to the iow of oil and when a sufficientquantity a chamber within the' combustion chamber and inclosing' the tip, and a conduit leading from the exterior of the combustion chamf ber to the said inclosing chamber.

2. In an oil burner, the combination'with an oil supply reservoir, of a vaporizing chamber, an oil supply passage leading from theoil reservoir to the vaporizing chamber, a gas chamber in communication with the vaporizing chamber and located beneath the same, a pan formed upon the top of the gas chamber, ribs reinforcing the sides of the and a tip in communication with the needle valve until such time as the pressure of the vapor is depleted by its consumption at the tip fw. he disadvantage. of this is that when the needle valve is closed the oil remaining in the inner portion ofthe pipe f will still feed notwithstanding the back pressure and to.overcome this and to provide acontrol immediately the gas pressureA rises .and falls, I have formed the en of the 'pipe f with the downwardly curted 4g 0r bent eid 4 or the equivalent thereof which the as chamber and situated below the latter. 3.
